Hey im having trouble playing some games, I have an nintndo DS lite with the R4, SanDisk 512mb micro SD and when i try to play some games that i recently just downloaded this is what it says " could not read the data. Turn off the power and reinsert the Game Card " and in some other games it starts to work but then it stops and says " Cannot access save data. Turn off the power and reinsert the DC card " Whats wrong? How come its like this? Thanks for all the help.
Yea, it just needs the firmware update and it will work just fine. I had the same problem and finally found a thread somehwere that told me that, but i dont have the website for the firmware update. But its only newer games that its doing this with.
